Abstract

An image display system includes: a background image transfer section which commands the image producing unit to produce a background image corresponding to the background image data and transfer the background image to the resolution adjusting unit; a window display image transfer section which commands the image producing unit to produce a window display image corresponding to the window display image data and transfer the window display image to the resolution adjusting unit; and a display control section which controls the process of the resolution adjusting unit for outputting the image stored in the virtual image storing unit.

1 . An image display system, comprising:
 a display unit which displays an image;   an image data storing unit which stores display image data;   an image producing unit which produces an image corresponding to the image data stored in the image data storing unit;   a virtual image storing unit which produces a virtual image corresponding to the image produced by the image producing unit and stores the virtual image;   a resolution adjusting unit which adjusts resolution of the image stored in the virtual image storing unit and outputs the adjusted image to the display unit; and   a control unit which controls the image producing unit and the resolution adjusting unit,   wherein
 background image data for a background image displayed on a display area of the display unit and window display image data for a window image displayed on a part of the display area are stored in the image data storing unit, and 
 the control unit includes
 a background image transfer section which commands the image producing unit to produce a background image corresponding to the background image data and transfer the background image to the resolution adjusting unit, 
 a window display image transfer section which commands the image producing unit to produce a window display image corresponding to the window display image data and transfer the window display image to the resolution adjusting unit, and 
 a display control section which controls the process of the resolution adjusting unit for outputting the image stored in the virtual image storing unit. 
 
   
   
   
       2 . The image display system according to  claim 1 , wherein the background image transfer section commands the image producing unit to produce an entire background image having resolution determined according to the resolution of the entire display area of the display unit and transfer the entire background image to the resolution adjusting unit. 
   
   
       3 . The image display system according to  claim 1 , wherein the background image transfer section commands the image producing unit to produce division background images created by dividing the background image and transfer the division background images to the resolution adjusting unit. 
   
   
       4 . The image display system according to  claim 1 , wherein the display control section commands the resolution adjusting unit to stop the process for outputting the image stored in the virtual image storing unit when the background image is transferred by the image producing unit. 
   
   
       5 . A game machine, comprising the image display system according to  claim 1 . 
   
   
       6 . An image display method used for an image display system which includes:
 a display unit which displays an image;   an image data storing unit which stores display image data;   an image producing unit which produces an image corresponding to the image data stored in the image data storing unit;   a virtual image storing unit which produces a virtual image corresponding to the image produced by the image producing unit and stores the virtual image;   a resolution adjusting unit which adjusts resolution of the image stored in the virtual image storing unit and outputs the adjusted image to the display unit; and   a control unit which controls the image producing unit and the resolution adjusting unit,   wherein
 the control unit performs
 a background image transfer step which produces a background image corresponding to the background image data for a background image displayed on a display area of the display unit and transfers the background image to the resolution adjusting unit, 
 a window display image transfer step which produces a window display image corresponding to the window display image data for a window image displayed on a part of the display area and transfers the window display image to the resolution adjusting unit, and 
 a display control step which controls the process of the resolution adjusting unit for outputting the image stored in the virtual image storing unit. 
 
   
   
   
       7 . An image display program used for an image display system which includes:
 a display unit which displays an image;   an image data storing unit which stores display image data;   an image producing unit which produces an image corresponding to the image data stored in the image data storing unit;   a virtual image storing unit which produces a virtual image corresponding to the image produced by the image producing unit and stores the virtual image;   a resolution adjusting unit which adjusts resolution of the image stored in the virtual image storing unit and outputs the adjusted image to the display unit; and   a control unit which controls the image producing unit and the resolution adjusting unit,
 the program allowing the control unit to perform:
 a background image transfer step which produces a background image corresponding to the background image data for a background image displayed on a display area of the display unit and transfers the background image to the resolution adjusting unit, 
 a window display image transfer step which produces a window display image corresponding to the window display image data for a window image displayed on a part of the display area and transfers the window display image to the resolution adjusting unit, and 
 a display control step which controls the process of the resolution adjusting unit for outputting the image stored in the virtual image storing unit. 
 
   
   
   
       8 . A storage medium on which the image display program according to  claim 7  is recorded in such a manner as to be readable by a computer.
